Abstract
A system and method is provided for learning, training and rehabilitation in which comparison is made of representative electrical signals produced by both a teacher (12) and a student (14) during attempted replication by the student (14) of a movement behavior demonstrated by the teacher (12), with corresponding feedback to the student (14) to inform the student (14) as to whether the replication is suitably compliant to the demonstration. The preferred embodiment is a myoelectric feedback system (10) employing wireless transmission of the myoelectric signals generated by the relevant muscles of the teacher (12) and the student (14) during the demonstration and attempted replication, with vibratory feedback to the student (14) upon comparison of the myoelectric signals at a remote processing station (18). A delayed or 'non-live' teaching capability is provided by a videotape processing machine (28) and a computer (30). An alternative embodiment provides that the video images of the demonstration performed by the teacher are stored in digitized form, e.g. on a CD-ROM (74). In the alternative embodiment, decision-making software (76) may be incorporated to provide for an interactive learning system.
